When to update statistics manually, if at all? Posted: 08 Apr 2013 06:59 AM PDT So, I'm using my google foo to try to find some articles about why we should not be updating statistics and recompiling on a daily basis. It is pretty clear that with auto_update_statistics enabled, there is no reason whatsoever to recompile after the statistics update. However, I cannot find any information about how to tell when we should update the statistics. I would like to believe that we shouldn't have to at all, but I have to convince myself of that as well. Instead of just saying "well, statistics are created and updated manually, so we don't need to update them daily." I need some references. Google is only showing me how to do it and what it does... not how to determine when I should do it. Any help appreciated. |

Can I SUM the 'LastPeriod' query results? Posted: 08 Apr 2013 12:57 PM PDT Hi,I want to create 'Rolling' Month on Month, Quarter on Quarter queries with Revenue data.So, for example if I want to create a Quarterly Reveneue variance (which I would calculate as the Last months Revenue minus the First Months Revenue & divide that revenue amount in to the Last months Revenue amount)My Quarterly query therefore needs to include the 'End Month' let's say June 2012 & contain the 'Billed_Amount' field to find the Revenue for a given month.I thought I'd use the 'Lastperiod' function to collect 3 months back from June 2012 & SUM those amounts to use in a variance calculation with the next quarter & so on.Here's my MDX query that I'm checking in SSMS to ensure it's correct before I add it to the Calculations in BIDS;SELECT LastPeriods(3,[MTH_QTR_HLF_YR].[Month].&[201206]) ON 0FROM [RM RADAR ACCT CUBE]This gives me the months I need & counts the records, OK so far...Then I add the 'Total_Billed' Measure to get the Revenue figures;SELECT LastPeriods(3,[MTH_QTR_HLF_YR].[Month].&[201206].[Measures].[Total Billed]) ON 0FROM [RM RADAR ACCT CUBE]I don't get anu results for this query, not sure why & I want to SUM these 3 'Total_Billed' amounts once this query works.So, I'm thinking I could then use this to SUM the 'Total_Billed';SELECT SUM(LastPeriods(3,[MTH_QTR_HLF_YR].[Month].&[201206].[Measures].[Total Billed])) ON 0FROM [RM RADAR ACCT CUBE]Can anyone suggest how I best use 'Lastperiod' OR should I use another Function altogether??Thanks |
Are Queries Actually Using the Index Posted: 08 Apr 2013 12:19 PM PDT Hello EveryoneI have a SQL database that is the backend to a Java application. There are indexes on the column in the tables. The java app does not use any stored procedures. It passes in all the queries from the front-end. Some are simple and some are dynamically built on the front-end.How can I see if the query that is being passed in, is actually using the index or performing a full table scan?It seems that some of the queries are taking a long time to return any data to the front-end. I just need to verify what is actually happening.Thank you in advance for all your assistance, comments and suggestions.Andrew SQLDBA |

Posted: 08 Apr 2013 11:26 AM PDT At work we have an application that has the ability to use 3 active directory groups to setup security within the application (Admin, User, Read Only). The application access a SQL Database (typically 2008 R2), and I am being told that I don't need to have these AD groups setup with the SQL environment (such as new login) for this authentication to work. However, we have been having problems with this setup for some time now, but the engineers who created this insist this works.We do use an AD settings file to direct it to the AD server and location, however, the specific groups are not a part of this file. The group names are stored within the SQL Database, so a successful authentication to the Database should be needed to obtain this information. Thus, I am being told, that once everything is setup, I should be able to connect in using a Windows Authentication, and our software will be able to accesses several databases within a single instance without any user information being listed in Management Studio. When I have tried to do this with the last few customers I have worked with, unless we setup the AD groups themselves within the SQL environment, we have not been able to get this to work.Any suggestions on what I could be doing wrong? Any assistance on how this could be working, or if it should be working at all would be greatly appreciated.ThanksLD |
New Linked Server Uses Local Catalogs - Not Those on the Remote Server Posted: 08 Apr 2013 09:07 AM PDT I have tried every way I can think of to define a linked server so that I can query catalogs on a remote production server. Problem is, when I expand the catalogs on the new linked server, it shows the catalogs on the local server where it's defined - and not the catalogs on the remote server! Could it be that the login on the remote server is invalid - so it defaults to the catalogs on the local server? Here's the code:EXEC master.dbo.sp_addlinkedserver @server = N'ProdServer', @srvproduct=N'SQL Server'EXEC master.dbo.sp_addlinkedsrvlogin @rmtsrvname=N'ProdServer',@useself=N'False',@locallogin=NULL,@rmtuser=N'RPTSUSER',@rmtpassword='########'This definition seems to work fine (no errors). But when I look at the catalogs, hoping to see those on the remote server, I see the ones on the current server. What am I missing here? Thanks! |
Posted: 07 Apr 2013 11:57 PM PDT Hey,I'm using MONTH and YEAR functions to match on current month and current year.

Publishing and accessing SQL Server 2008 Reports Posted: 31 Mar 2013 12:20 PM PDT I 'm new to SQL Server database and I need help. I 'm trying to publish sql reports for users to access from the web. We have SQL server 2008 database with data, and I have installed a separate SQL server 2008 with Reporting Services on my windows xp machine. I have created data source from the remote sql server 2008 installed on a Windows Server, and publish the reports. I can access the report manager through the URL (//localhost:8080/ReportServer) on my xp machine browser. However, when I typed the same URL from another computer, I get page cannot be displayed message. What is going on? Does the report manager URL needs to be configured on the SQL Server that has the database instance? Please help. ThanksTo make myself clear, what I 'm trying to acomplish is to create and publish reports for users to access from their workstations. Any help will be appreciated. |

How to NOT match on an exception list Posted: 08 Apr 2013 05:10 AM PDT If I have a table of Products that have a ProductName and I have a table of ProductNames that I don't want the first table matched to, what is the best process in which to do this? The names will be LIKE each other, but will not match exactly. When I pull data, I only want the ones from dbo.Products where they don't look like the Products from dbo.Exceptions. In my example, I want to pull back Products that don't look like WidgetD or WidgetE. Normally I would write: SELECT ProductDesc FROM dbo.Products WHERE ProductDesc NOT LIKE '%WidgetD%' AND ProductDesc NOT LIKE '%WidgetE%'The query should return WidgetA, WidgetB, and WidgetC (3 records)However, I don't want to jack with the code every time a new exception is added. Is there a better method? (example code below)CREATE TABLE [dbo].[Products]( [ProductDesc] [varchar](200) NULL) INSERT INTO Products(ProductDesc) SELECT 'WidgetA'INSERT INTO Products(ProductDesc) SELECT 'WidgetB'INSERT INTO Products(ProductDesc) SELECT 'WidgetC'INSERT INTO Products(ProductDesc) SELECT 'WidgetD'INSERT INTO Products(ProductDesc) SELECT 'WidgetE'CREATE TABLE [dbo].[Exceptions]( [ProductDesc] [varchar](200) NULL) INSERT INTO Exceptions(ProductDesc) SELECT 'Big WidgetD'INSERT INTO Exceptions(ProductDesc) SELECT 'Small WidgetE' |

Tracking a change to the notifications on an Agent job Posted: 08 Apr 2013 01:34 AM PDT Hi everyone,So I've had someone change the notifications, specifically the Page: nofitication on all agent jobs on our production server. It's easy enough to change this back to it's correct value but I'm wondering who did it. Do these get logged anywhere by default, or do I have to enable logging in some way to catch it in the future (which does me no good on this instance). Thanks |
Posted: 08 Apr 2013 01:29 AM PDT Good morning. I have been working on a faster solution for some time, and thought I had it. I have a very large table with all people who work in the state. I need to join that table to a much smaller one of college graduates for outcomes. Since the graduates table will continue to grow, I can't remove anyone from the wage table. So wage table remains huge, and will only get bigger. Now, joining the tables is not a big deal, but for the fact that people often work in more than one job. But I created a table-valued function:CREATE FUNCTION dbo.GetWages (@SSN char(9))RETURNS TABLEASRETURN SELECT year, quarter, ssn, SUM(hours) hours, SUM(wages) wages, SUM(wages)/nullif(sum(hours),'0') rate FROM dbo.Wage_data WHERE ssn IN (@SSN) GROUP BY year, quarter, ssn;GOAnd it works great: SELECT student_id, LName, rateFROM dbo.Degrees_Data CROSS APPLY dbo.GetWages(SSN)However, we also want to know the industry of employment. When there are two jobs, we want the industry of the main job, defined as one with most wages. To get this, I have been using a CTE in a view, which is very slow since I cannot write in index to it. So again I wrote a TVF:CREATE FUNCTION dbo.GetWagesAndIndustry (@SSN char(9))RETURNS TABLEASRETURNWITH cte AS ( SELECT year, quarter, ssn, hours, industry , ROW_NUMBER() over (partition by year, quarter, ssn ORDER BY wages ASC) rn , SUM(wages) over (partition by year, quarter, ssn ) SumWage , SUM(hours) over (partition by year, quarter, ssn ) SumHours FROM dbo.Wage_data WHERE ssn IN (@SSN) )SELECT year, quarter, ssn, industry, SumHours hours, SumWage wages, SumWage/NULLIF(SumHours, '0') rageFROM cte WHERE rn = 1But this is also painfully slow. Eventually we want to be able to create reports on the aggregated data, but who's going to wait 5-10 minutes for a report to generate? Definitely, not my boss. There must be a creative way to group the wage data to one record per person, yet have the industry information still available. What am I not seeing? Thank you for any help. |

Corruption - Renaming of system data databases to ldf :( Posted: 02 Apr 2013 10:34 AM PDT Hi,This morning a made a proper boo boo while building a new SQL Server 2008 R2 install. After the installation had completed I wanted to move the system databases to a new drive.However when moving the log files I executed the following T-SQL in error:ALTER DATABASE [master] MODIFY FILE ( NAME = master , FILENAME = 'J:\Log\SystemLog\mastlog.ldf' );ALTER DATABASE model MODIFY FILE ( NAME = modeldev , FILENAME = 'J:\Log\SystemLog\modellog.ldf' );i.e. I renamed the data files to ldf's.....As a result I cannot start the SQL Engine and get the following error in the ERRORLOG on startup:2013-04-03 10:12:40.74 spid9s Error: 5171, Severity: 16, State: 1.2013-04-03 10:12:40.74 spid9s J:\Log\SystemLog\modellog.ldf is not a primary database file.2013-04-03 10:12:40.77 spid9s Error: 945, Severity: 14, State: 2.2013-04-03 10:12:40.77 spid9s Database 'model' cannot be opened due to inaccessible files or insufficient memory or disk space.

*MAY* need to switch DBs from Full Recovery to Simple, due to backup space issues... Posted: 03 Apr 2013 02:52 AM PDT First and foremost, I'm working with our backup admin to find a better solution for the problem, that won't require doing this.Second, adding capacity to the backup system would be nice, but by the time the request were to make it through the bureaucracy here, we'd be migrating to SQL3010...:hehe:So the scoop is, the backup system here ran out of room for the Sharepoint SQL DBs, and now myself and the backup Admin are trying to get it working again. She's limited in what she can do by the retention policies, I'm limited by the fact that it's Sharepoint, so no going in and dropping rows from big tables...(The Sharepoint Admin is on vacation, to boot...)So I think what may have set the problem off was the SP admin, after realizing that the previous admin had enabled auditing of EVERYTHING and did not set up the "trim" option to only keep a month or so worth of entries, tried to delete out old records. With the DBs being in Full recovery, the TLogs got rather full.Then the backup ran out of space because of this (I think the retention is 30 days, then it goes to tape)So my worst-case solution to reduce the size of data in the TLogs is to do the following:1. After-hours, switch all DBs from Full Recovery to Simple, sacrificing point-in-time recovery2. After SQL has "truncated" the logs, switch back to Full Recovery3. Let the early AM Full DB backup run, and get back on our bi-hourly TLog backupsYes we lose PiT recovery, but right now we have NO recovery since yesterday...Yes, I should have caught this sooner.So, a question:About how long might it be before SQL auto-truncates the logs? Can I "force" it to happen sooner by issuing a "Checkpoint" on the DBs, and could it take more than one checkpoint?I'm not currently planning to shrink the physical files, so that SQL doesn't need to "grow" the file later.Thanks,Jason(As an example, one of the Log files is showing 18655.19MB used in the log... I had been monitoring the sizes of the DBs and TLogs for a couple weeks, looking to free up some disk, and this DB averaged 402MB...) |
